I think 'Accept Ents Speak' would be fine, so as to illustrate that fans of the Tolkien masterpiece accept that Ents do indeed speak.
Or rather, accept that in the context of the story, Ents speak. I am not suggesting that fans of the Lord Of The Rings accept the actual existence of Ents... Much as it would make life more interesting if they did stroll around the countryside (Ents that is, not fans of the books. Barely have time to walk around as we spend too much time watching the extended versions of the films, behind the scenes blogs etc)
